non {amd64,i386} files vanished from security.u.c

[Andrew Vagin]

We use docker and qemu-static to build our project for all supported arch-es in travis. But a few days ago a ppc job started to fail with this error:

Here is a full log:
https://travis-ci.org/xemul/criu/jobs/263720066

[Julian Andres Klode (juliank)]

The files went away from the mirror, but are listed as available. Reassigning to launchpad.

[Julian Andres Klode (juliank)]

More specifically, the release file says:

 cb7930bc03f003db8090a500bc7bdfe8 3217912 main/binary-ppc64el/Packages

So the file exists according to it and is not empty, but in practice there are no binary-ppc64el directories everywhere. Same for arm64, armhf, powerpc (anything not amd64, i386).

[Julian Andres Klode (juliank)]

Same for all other releases, not just trusty.

[Pavel Emelyanov (xemul)]

Here: https://github.com/xemul/criu/issues/376 we were told that
"ppc64el is a ports architecture, and therefore the security pocket is hosts on ports.ubuntu.com/ubuntu-ports not on security.ubuntu.com domain."
